The horizontal scale capability of the ThingWorx Connection Servers can also be used to deploy a high availability configuration of them. Once the functional need is determined, you can work out the high availability requirements.

For example, it has been determined that two connection servers are required to meet functional demands. If the high availability SLA requires at least 25% redundancy, then one extra connection server should be added to the deployment.

Deploying connection servers in an HA environment is no different than deploying to a non-HA environment. Please follow the installation and configuration guidelines provided in the ThingWorx Connection Server section of the ThingWorx Connection Services Help Center.

To complete the HA configuration for the connection servers, all traffic to the ThingWorx connections servers must be routed to them through a load balancer. Please refer to the load balancer discussion in Load Balancers for ThingWorx High Availability.
